1. Technical Field
The present invention relates to electrical connectors, and more particularly, to an improved electrical connector that can transmit high-definition (HD) digital signals through a first terminal assembly and a second terminal assembly simultaneously and obviate electromagnetic interference (EMI) and improve disturbance by covering the first terminal assembly and the second terminal assembly with a first housing and a second housing, respectively.
2. Description of Related Art
With the advent of the digital audio & video (AV) times, various hardware equipment associated with 3C AV products have been constantly developed and upgraded. For connection between different hardware equipment, demands on associated electrical connectors also become ever higher accordingly.
Among the digital AV products, liquid crystal displays (LCDs) for use with computers and high-definition (HD) liquid crystal TV sets for home use are the best sold ones. Therefore, digital AV products capable of outputting digital AV signals directly have been developed by the manufacturers in succession for use in combination with the LCDs and HD liquid crystal TV sets, for example, computer display cards, Blu-ray DVD players, HD projectors and the like. All these products are provided with at least one connector that is known as a digital visual interface (DVI).
As a kind of electrical connector for use to transmit HD digital AV signals, the DVI connector is able to transmit both digital signals and analog signals, and support digital video display apparatuses such as HD liquid crystal TV sets. The DVI connector is adapted to transmit uncompressed HD digital video signals, and can provide high-quality large frames free of radiations to allow the user to enjoy a better visual effect.
Most of the conventional DVI connectors that are currently used are of a single-layered structure, which is unable to meet with demands for use of multiple screens. Moreover, the conventional DVI connectors failed to have transmission terminals thereof particularly adjusted in length, width and thickness to minimize the equivalent capacitance during transmission. Therefore, electromagnetic interference and electromagnetic susceptibility might occur to the conventional DVI connectors during high-frequency transmission, causing failure in fully providing the expected performance.
Accordingly, in view of the drawbacks and shortcomings of the conventional DVI connectors, the present inventor has made great efforts to make improvement thereon, and finally provides an improved electrical connector of the present invention.
The primary objective of the present invention is to provide an improved electrical connector, which can transmit high-definition (HD) digital signals through a first terminal assembly and a second terminal assembly simultaneously and, by covering the first terminal and the second terminal with a first housing and a second housing, respectively, obviate electromagnetic interference suffered by the first terminal and the second terminal during high-frequency transmission, thereby improving the electromagnetic disturbance susceptibility.
Accordingly, to accomplish the above-mentioned objective, the present inventor proposes an improved electrical connector for use to transmit high-definition (HD) digital images. The improved electrical connector comprises: a body, being provided with a terminal connection base; a first terminal assembly, being connected to the terminal connection base at an end thereof and configured to transmit a signal; a second terminal assembly, being connected to the terminal connection base at an end thereof and configured to transmit a signal; a first terminal connecting device, being disposed on the body and having a first connecting body for receiving the first terminal assembly therein; a second terminal connecting device, being disposed on the body and having a second connecting body for receiving the second terminal assembly therein; a first housing, covering the first terminal assembly and being adapted to maintain the integrity of signal transmission of the first terminal assembly; and a second housing, being disposed on the body and covering the first housing to prevent electromagnetic interference (EMI) suffered by the first terminal assembly and the second terminal assembly during high-frequency transmission and improve the electromagnetic disturbance susceptibility.
The invention as well as a preferred mode of use and advantages thereof will be best understood by referring to the following detailed description of an illustrative embodiment in conjunction with the accompanying drawings, wherein:
To describe the improved electrical connector proposed in the present invention more clearly, a detailed description will be made with reference to the attached drawings.
The body 11 has a major side 113 and a minor side 114 which are perpendicular to each other to form an L shape, and a terminal connecting base 111 is disposed on the minor side 114.
The first terminal assembly 12 is connected to the terminal connecting base 111 at an end thereof. Referring to
The second terminal assembly 13 is connected to the terminal connecting base 111 at an end thereof and adapted to transmit a signal. In this embodiment, the second terminal assembly 13 has a short length and, therefore, needs not to be took any angular bend to decrease the impedance. However, as with the first terminal assembly 12, the second terminal assembly 13 of this embodiment also has a width and a thickness of terminals thereof varied in order to obtain a better signal transmission effect.
The first terminal connecting device 14 is disposed on the major side 113 of the body 11 and comprises a first connecting body 141. The first connecting body 141 has a plurality of first receiving holes 1411 for receiving the first terminal assembly 12 therein. Furthermore, through the first connecting body 141, the first terminal assembly 12 can be connected to external terminals.
The second terminal connecting device 15 is disposed on the body 11 and comprises a second connecting body 151. The second connecting body 151 has a plurality of second receiving holes 1511 for receiving the second terminal assembly 13 therein. Furthermore, through the second connecting body 151, the second terminal assembly 13 can be connected to external terminals.
The first housing 17 covers the first terminal assembly 12. Referring back to
The second housing 18 is disposed on the body 11 and covers the first housing 17. Preferably in this embodiment, the second housing 18 is a metal housing. By using the first housing 17 and the second housing 18 to cover the first terminal assembly 12 and the second terminal assembly 13 simultaneously, this embodiment can obviate the problem of electromagnetic interference suffered by the first terminal assembly 12 and the second terminal assembly 13 during high-frequency transmission, thereby improving the electromagnetic disturbance susceptibility.
The two harpoon-shaped terminal assemblies 16 are disposed at two sides of the minor side 114, respectively, and each has two harpoon-shaped terminals. Hence, by means of the harpoon-shaped terminal assemblies 16, the improved electrical connector 1 can be installed on an external printed circuit board (PCB).
